Dorene Sanchez

A woman who drove two defendants away from Dodger Stadium the night that a Giants fan was attacked planned to testify Thursday in the suspects’ preliminary hearing as prosecutors near the end of their effort to prove the men should stand trial.

The District Attorney’s Office has decided not to file charges against Dorene Sanchez, who was initially arrested with the two suspects in the beating of Giants fan Bryan Stow at Dodger Stadium on opening day.
